Ryoto, Frontline Marshal

Whenever a creature with flying enters the battlefield, put a flying counter on Ryoto,
Frontline Marshal. The same is true for first
strike, deathtouch, hexproof, indestructible, lifelink, menace, trample, and vigilance.
{2}, Remove a counter from Ryoto: If a keyword counter was removed this way, other creatures
you control gain that keyword ability until end
of turn. Otherwise, they get +1/+1 until end of
turn.
